Deleted child etries still exists in navigation property of cached parent record

[Pavel]

So i want to know, may be i uncorrectly configured my model, but when i delete child record, it still cached in parent navigation property and application stuck in error like "No record for row..."

My navigation properties is not marked as dependent or managed, i delete child record as follows

db.Delete(child);

and then getting error when accessing parent.childs collection, that still contains that deleted child.

Read http://docs.telerik.com/data-access/developers-guide/crud-operations/manage-navigation-properties/developer-guide-manage-navigation-properties-one-to-many.

Then add IsManaged to your parent.children association configuration.

I know about this, we dont use navigation properties to manage relationships.

In addition, this article does not say that this method changes the behavior of the navigation properties when you delete items. Those. it does not say that if I use IsManaged, navigation property will be correctly updated by removing cached item from them.
